To all whom it may concern."

Be it known that LFREDERICK H. ROBERT- soN, a. citizen of the United .States, and resident of Cleveland, in the county of Guyahoga and State. of Ohio, have invented certain new and useful Improvements'in Wind- 7 i vide an improved form of wind shield cleaner which can readilyfbe attached to any mod em form'of windshield and-which combines the advantages'of perfect contact with the surface'of the glass shield with ease of movement and is guided, upon the frame of the wind shield without doing any injury to the enamel or,finish thereof.

The ,invention'is adaptable to use with the wind shield of vehicles of any character -but is exemplified in its use in the wind shield of an automobile, and movable upon the upper edge of its frame.

The invention comprises the combination and arrangement ofparts and construction of the several detail parts,- hereinafter de-"- scribed, shown in the accompanying drawings and specifically pointed out in the claims.

the wind shield, and which rolls upon the upper edge of the frame at D.

'Thednner arm C of this bar is provided with'a'roller E which traverses the inner face of the wind shield as the device is moved from one point to another thereon.

The outer arm 10 ofethe device is longer than the inner arm so arm extend below 1t, and a supportin back member or keeper F which supports t e wiping strip G is seback for the wiping strip are preferably formed of spring metal so that the wiping strip can be removed when worn out and end the supporting back F is secured between the sides of a gripping member-J and a spring H. attached preferably to the back F engages the rod C and always tends'to press the upper end of the Wiping strip into contactwith the glass. I This spring attachment is required, since otherwise, the action of the spring arms In the accompanying drawingsFigure 1- would confine the pressureto'the lower ends thereof, and only the lower edge of the wiping strip would-make contact with the glass.

Therefore, by pivoting the lower end of the back piece F and placing the upper end under spring pressure, the entire wiping edge will be made to contactwith the glass surface under pressure. I M

The gripping strip and back member for the wiping strip are preferably ribbed or corrugated at K, K, so as to make thegconnection rigid and secure. The longer arm 0 serves as a'brace for the device to prevent tilting the member G transversely of the another substituted therefor. At the upper.

To prevent the device from swinging backward and forward upon the roller when operating, a rigid bar L-iscentrally attached io o be drawn down thereon when it is desired,

to release the device from the wind shield.

The spring action of the arms and of the spring serves tokeep the rollers in close contact with the glass and with the corner-be- I tween the glass and edge'of' the frame, so that while the device moves easily it ls'retained in accurate vertical alinement and cannot be twisted or swun out of placej In Figs. 7 and-8 a modi ed form, of support P for the cross bar is shown, which is provided withthe vertical :s'lott) having an extension at anangle at Q, to permitthe bar L to be dropped and withdrawn so'that the cleaning device can be released from the windshield, a stud R movable in a slot R is secured in place by means'of a nut S.

When this device is used it will not be necessary to bend the U shaped rod C outwardly. j v

Having described the invention, what I claim as new and desire to secure by Letters Patent is:

. 1. In a cleaning device for a glass Wind shield, the combination with an integral U shaped spring bar provided witha roller adapted to traverse the frame of said wind shield, the extremities of said barbent substantiallyp'arallel to each other to overlap the sides of said Wind shield,'.one arm being longer than the other, of a wiping strip attached to the longer arm, and aglass engagmg means on the lower end of the short arm,

the elongated arm tending toprevent tilting the cleaning device transversely of the wind shield, a rigid bar centrally and adjustably,

. secured upon said short. arm and rollers spaced thereon engaging the in'neredge of said frame. l

2. In a windshield cleaner, a U. shaped spring bar one of its arms being longer than the other, a roller mounted thereon and space adapted to traverse the frame of said wind shield, a roller at the extremity of said short arm engaging the inner face of said wind shleld, and a w p ng strl'p pivotally secured to the lower end of said longer arm, a spring interposed between the upper end of said wipin 'strip and its attached arm, and

(I guiding and-retaining means secured to one ofsaid arms and engaging said frame is movable up and down upon,

at the angle therecif with the glass, said guid- 4 ing and retaining means preventlng vertical and oscillatory movement thereof.

3. In a cleaner for awind shield having a frame, a U shaped spring bar, one,arm there of engaging the inner side of said shield at its inner end, a wiping strip pivotally at tached to the lower end of the other arm, and a spring interposed between the upper end of said wiping strip and itsattached arm, a cross bar on one arm having rollers at its outer'extremities engaging the lower edge of the upper bar of said frame, and se curing means for said cross bar.

' 4:- In a wind shieldcleanera U-shaped spring bar, one of its arms being longer than the other, a roller mounted thereon intermediate of the arms and adapted to traverse the edge; of the frame of said wind shield, a roller at the extremity of said short arm engaging the inner face of said wind shield, a

wiping strip pivotally'secured to the lower end of the longer arm, a. spring interposed between the upper end of said wiping strip and its attached arm, and a laterally spaced means secured to one of said arms and en gaging said frame at the angle of the inner edge thereof with the wind shield, prevent ing vertical and oscillating movement of said cleaner, substantially as described.

5. In a cleaner for a wind shield having a frame, in combination, a U shaped spring bar having inner and outer arms, one arm thereof engaging the inner face of said shield at its'lower end, a wiping edge attached to the other arm, a rigid cross bar secured to the inner arm, and a roller at each extremitythereof, each roller engaging the lower edge of the upper bar of said frame, saiciiinner arm bent outwardly at its lower en 6, In a cleaner for a wind shield having a frame, in combination,- a U shaped bar, a roller mounted thereon intermediate of the arms, and adapted to traverse the edge of the frame'of said Wind shield, a roller pivoted in the lower extremity of the inner arm, a wiping strip. and backing therefor pivomlly attached to the outer arm, a spring inter-' posed between the upper end of said backing and the arm,.and a rigid cross bar secured at its center to one of said arms adjacent'to its upper end, rollers pivoted thereon, said rollers'being equally spaced from the said arm and engaging the inner edge of said frame.
